Currently, there are more patients with Parkinson's disease. Freezing of gait (FOG) problems and decreased first step length during gait initiation were found to be prone to falls, the poor activity in daily life, self-help is more difficulty, bedridden and disability in the future. Therefore, external cues as an alternative to training for stimulating and target the patient while walking. This study examined the effects of laser light visual cueing on freezing of gait and first step length in patients with Parkinson's disease.
Purpose: The purpose of this study was to effects of laser light on freezing of gait and first step length in patients with Parkinson's disease.
Methods: Eleven patients with Parkinson's disease (aged 40-85 years) both men and women who had a modified Hoehn and Yahr scale of 2 to 3. The samples were drawn for testing divided into 2 conditions; no cue and laser light. The samples were tested with laser light on the anterior body around five lumbar vertebrae (L5) to collect the percent of time spent freezing and the length of first step length (Left and right first step length). Data were analyzed using mean, standard deviation and Paired-Sample T Test. The level of statistical significance was 0.05.
Results: The results showed that no cue significantly increased the percent time spent freezing compared to laser light (p<0.05). The first step length significantly increased when compared between laser light to no cue (p<0.05).
Conclusion: Laser light visual cueing diminished freezing of gait (FOG) but enhanced longer first step length in patients with Parkinson's disease.
